MSMQ trigger

[tommy]

Apart from designing a timer to examine the queue, I know
that the new version of MSMQ over XP/2003 platform
provides a way called 'MSMQ trigger', anyone had some
experience of using it from programmer's point of view?

thanks in advance

MQT is fine as long as you don't want to get fancy. The problem I've always
had with it is that it supports only executables and COM objects invoked via
IDispatch, which is very slow. And executables of course are separate
processes.

The "ideal" queuing dispatch service uses a well-known interface that it
controls and client "handlers" can then implement. In COM then just knowing
the ProgID of the implementation gets you to the finish line.

However, if your needs are not too complicated then the service encapsulates
a *lot* of functionality that is otherwise difficult and expensive to write.
